Japanese PM Shinzo Abe has been making noises about revising the country's pacifist constitution--and this time not just in the interpretation. The talk comes in the wake of, and in apparent reaction to, the recent killings of two Japanese hostages by ISIS.

Article 9 of the Japanese Constitution, the pacifist provision, reads:

Renunciation of War. Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as a means of settling international disputes.

In order to accomplish the aim of the preceding paragraph, land, sea, and air forces, as well as other war potential, will never be maintained. The right of belligerency of the state will not be recognized.
